' IMPROVEMENT -1N S'I'oP-eopcx BOXES -EoR WATER AND Gas-MAINS.

The Schedule referred to in these Letters Patent andrnkiug part of the san-1e.

To all whom it ana/y concern:

Be it known that I, ORIN Il. WOODFORD, of the city of Ohicago, in the county of Cook, and State-of V To enable others skilled in the art to`constrnct and use my invention, I will proceed to describe it.

Figures 1 and2 represent sections of the stop-cockand stop-cock box.

' The present mode of connecting stop-cocks ofwvater laid under ground, with the surface of generally, in a loosely-jointed, square',rwooden box, has this great inconvenience, that when the ground is saturated with water, this water penetrates into'and fills the wooden box, and in winter time,.being frozen therein, makes it. impossible to shut. o' water oregas in J(he pipes, without cutting ont the box itself. v

My invention having the purpose'to obvate the above-said difticulty, its nature consists in a watertight tube, to be used in place of the said wooden box, said tube being so arranged, that when affixed to the stop-cock of the water or gas-pipe, rendersV the connection ot' the said stop-cock with the surface of the y ground, water tight'.

, A is the stop-cock, the shell, B, of which, is somewhat cnlarged, and provided on the outside with a screw-thread, b, and a shoulder, c.

Dfis a water-tight tube, provided on the inside, at the lower end, with a screwthread, d, to fit the screw-thread b of the shell, and

when screwed on, to rest on the shoulder c.

'Ihe vtube D extends upward to the surface of the ground, the cap E being screwed on the ltop of it.

The tubegD may be made of metal, solid wood,

wood and metal combined, or of any other suitable material that would render the said tube watertight.-

Instead of screw-threads band d, the connection between the tube D and the stop-cock A, may be made' Ilya-coupling, or by some other water-tight device or attachment, rendering the said connection water-tight. l

That I claim as ne w,'and desire to secure by Letters Patent, is-

The tube D, attached to the shell B of the stopcock, or to .the snpply-pipe, in .such a manner as' to form a water-tight case, 'extending up to the surface, and enclosing the stop-cock A, as and for the purpose herein set fort-l1.
